Amber Orrange added 15 points on 7-for-9 shooting, six assists and two steals for Stanford (25-2, 14-1 Pac-12), which has won 27 straight games against Oregon State and also owns a 27-game home winning streak against the Beavers at Maples Pavilion.

Joslyn Tinkle went over the 1,000-point mark early in the second half and hit two late 3-pointers to finish with 11 points as Stanford stayed unbeaten in its last 11 games since a 67-55 loss to rival California at home on Jan. 13. The sixth-ranked Golden Bears beat Oregon 77-55 in Berkeley, so Stanford kept pace atop the conference standings.

Ogwumike, coming off a 26-point performance in a 68-57 win at UCLA last Sunday, also had four blocked shots and two steals. Her highlight came on an acrobatic swish in which she released the ball from beneath the backboard while falling out of bounds into a cameraman after being fouled. The three-point play put the Cardinal ahead 65-35 with 11:26 remaining - though Ogwumike didn't initially know she had scored until seeing her teammates cheer and raise their arms.

On that play, Ogwumike also set a career high with 11 made free throws as Stanford shot 16 for 18 from the line. Sophomore Taylor Greenfield matched her career high with 18 points for Stanford, which shot 48.5 percent from the field.

Beavers leading scorer Jamie Weisner scored 12 points to lead cold-shooting Oregon State (9-18, 3-12), which went 22 of 68 from the floor for 32.4 percent in losing its ninth straight game.

After Oregon State pulled within 12-11 in the first half, Stanford used a 16-4 run to pull away.

The Beavers shot 2 for 10 from 3-point range in the first half, missing six of their first seven. But they crashed the boards for 11 first-half offensive rebounds and held a 22-21 edge in the opening 20 minutes. The Cardinal wound up with a 46-34 rebounding advantage.

Stanford, which already has secured a first-round bye for the conference tournament in Seattle, leads the all-time series 51-6. The Cardinal wrap up their regular-season home schedule Sunday afternoon against Oregon before hosting the first and second rounds of the NCAA tournament in Maples next month.

Cardinal guard Toni Kokenis didn't dress and missed her fifth straight game with an undisclosed medical condition that has limited her all season. She last played on Feb. 3 at Oregon State.
